PROBLEM TO BE SOLVED: To provide an infrared gas analyzer which analyzes even such sample gas as with a lot of interference components, with high precision. SOLUTION: On one side of a measuring cell 2, an infrared light source 1 is provided, and the other side a non-selective detector 6 for detecting measuring components, and further between the measuring cell 2 and the non-selective detector 6, a half mirror 5 consisting of an interference filter, which permits the transmission of the spectrum only of the central wavelength in the measuring components, are provided, and a compensating detector 8 is provided on the reflection side of the half mirror 5, with a compensating interference filter 7 in between. |
